8 MHz higher effective memory clock speed. The effective memory clock speed is calculated from the size and data rate of the memory. Higher clock speeds can give increased performance in games and other applications.

Significantly lower TDP

Comment

134 W

vs

180 W

46 W lower TDP. The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

1.31 TFLOPS higher floating-point performance. Floating-point performance is a measurement of the raw processing power of the GPU.

113

Newer version of DirectX

Comment

11.2

vs

11

Newer version of DirectX. DirectX is used in games, with newer versions supporting better graphics.

99

Clearly higher pixel rate

Comment

35.2 GPixel/s

vs

15.7 GPixel/s

19.50 GPixel/s higher pixel rate. The number of pixels that can be rendered to the screen every second.

60

Newer version of OpenCL

Comment

1.2

vs

1.1

Newer version of OpenCL. Some applications use OpenCL to utilise the power of the graphics processing unit (GPU) for non-graphical computing. Newer versions introduce more functionality and better performance.

40

Explicitly more shading units

Comment

1280

vs

768

512 more shading units. Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.

118 MHz faster GPU turbo speed. When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

34

Substantially more memory bandwidth

Comment

192 GB/s

vs

144 GB/s

48 GB/s more memory bandwidth. This is the maximum rate that data can be read from or stored into memory.

32

Significantly more DisplayPort outputs

Comment

1

vs

0

1 more DisplayPort outputs. Allows you to connect to a display using DisplayPort.

32

Significantly wider memory bus width

Comment

256 bit

vs

192 bit

64 bit wider memory bus width. A wider bus width means that it can carry more data per cycle. It is an important factor of memory performance, and therefore the general performance of the graphics card.

32

Significantly more render output units (ROPs)

Comment

32

vs

24

8 more render output units (ROPs). The ROPs are responsible for some of the final steps of the rendering process, writing the final pixel data to memory and carrying out other tasks such as anti-aliasing to improve the look of graphics.
